Seagrasses are a valuable but threatened part of coastal systems. To aid restoration attempts, a model has been made to study the effect of such flexible aquatic vegetation on flow and sediment transport. Because this model needs to be tested against field results, a field experiment was undertaken around an eelgrass meadow in Dinard, France. The measurements showed larger flow velocities and higher sediment concentrations outside the meadow. The model showed similar behaviour, though the exact values differed.
